2 Claims. (C1. 2-195) This invention relates generallyio caps, but hasreference more particularly to a cap which is insulated against hightemperatures A primary object of the invention is to provide a cap ofthe character described, which is provided with a layer of insulatingmaterial, which efiectively insulates the head of the wearer against theeflects of high temperatures, but Which does not appreciably increasethe weight of the cap.

Another object of the invention is to provide a cap of the characterdescribed, in Which the heat insulating layer is permanentlyincorporated in the cap without means other than are conventionallyemployed in manufacturing the cap.

A further object of the invention is provide a cap of the characterdescribed in which aluminized cloth is employed as the insulating layer.

Other objects and advantages cf my invention will be apparent during thecourse of the following description.

In the accompanying drawings forming a part of Ihis specification and inwhich like numerals are employed to designate like parts throughout thesame,

Fig. 1 is a perspective view of a cap embodying the invention;

Fig. 2 is an enlarged view of the cap, partly in side elevation, andpartly in cross-section, taken on the line 22 of Fig. 1;

Fig. 3 is a fragmentary view, partly in elevation and partly incross-section, taken on the line 3-3 of Fig. 1, with theshape-maintaining ring in osition, and

Fig. 4 is a fragmentary cross-sectional view, taken on the line 44 ofFig. 3.

Referring more particularly to the drawings, it will be understood thatalthough the invention is shown and described in connection with amilitary cap, that it may be used in connection With conventional typesof dress caps, shop caps, chauffeur caps, as well as in connectiou withhats.

The cap will be seen to comprise a cap body, generally designated byreference numeral 1, a band portion 2, which is secured -to the capbody, and a visor 3, which is secured to the band ortion 2.

The body portion consists essentially of an upper fabric portion 4 and alower fabric portion 5. The portion 5, in accordance with conventionalpractice, may consist of three segments which are sewn together at theirends.

Disposed immediately below the fabric portion 4 is a layer of aluminizedcloth 6, Which consists of a closely woven thin flexible fabric, theupper surface of which is provided with an extremely thin deposit orplating 7 of pure aluminum, which is flexible and has been found to havea higher degree of heat reflectivity than most aluminum paints, althoughthe possibility of using an alnminum paint in lieu of such deposit orcoating is not precluded. Such aluminized cloth is available fromseveral sources, but has not heretofore been utilized for the purposesfor which it is used in the present invention.

Disposed immediately below the cloth layer 6 is a cap lining 8, which isshown as made of a fabric having a dull upper surface, and glossy lowersurface.

Disposed immediately below the lining 8 is a layer o1 film 9 of clear ortranslucent plastic, which has a watetproofing function and prevents thelining from becoming soiled by the head of the wearer.

The elements 4, 6, 8 and 9 are of generally circular form, and, With theexception of the element 9, are provided at their peripheral edges withinturned hems 10, 11 and 12, respectively, which are sewn, as by a lineof stitching 12a, to the inturned hem 15 of the lower fabric portion 5of the cap, so that the hemmed edges are in contiguity With each other,as at 17.

There is also provided an annular protective fabric strip 14 providedwith hemmed edges to which the hemmed edges of the elements 4, 6 and 8are sewn, as by a line of stitching 13, and to Which the hemmed edge ofthe portion 5 is sewn, as by a line of stitching 16.

The layer 9 of plastic is sewn, as by a line of stitching 18, the lining8.

The cap further includes a rernovable ring-like member or grommet 19,which is disposed Within the cap, adjacent the joint 17, and whichserves to 1retain or maintain the cap in circular form.

The details of construction of the band 2, visor 3, and other parts ofthe cap other than those described above, are more or less conventional,and need not be further described.

The aluminum coating 7 of the cloth layer 6 functions to reflect heatrays impinging upon the top of the cap, thereby preventing such raysfrom passing through the layers 6, 8 and 9. In this manner, the head ofthe wearer is not subjected to the intense heat of the sun, but ismaintained fairly cool, permitting the wearer to remain fairlycornfortable for prolonged periods, even in excessively hot outsidetemperatures. In actual tests made under practical conditions, it hasbeen determined that at outside temperatures cf about 114 F. thetemperature directly under the cap, above the head of the wearer, ismaintained at about 98 F. This, of course, represents extremeconditions, and at lower temperatures, the efficiency of cooling,produced by the aluminized cloth is even greater.

The layer of aluminized cloth is extremely light and thin, so that itdoes not appreciably increase the weight cf the cap, and does not,therefore, result in any discornfort to the wearer.

By securing the layer of alurninizecl cloth to the cap by the same meansWhich a1e conventionally employed in securing the lining in the cap, thealuminized cloth is permanently incorporated in the cap without the useof special or extraneous seouring means, so that the cost of manufactureof the cap is not appreciably increased.

Caps with such a built-in heat insulating layer are especiallyadvantageous for use by military policemen, civil policemen, and otherswho conventionally wear this type cf cap.

Various modifications are contemplated as corning Within the scope ofthe invention. Among these are the following:

(a) The lining 8 may be reversed, so as t0 dispose the glossy surfacethereof as the upper surface.

(b) The lining 8 may be eliminated, if desired, in Which case thealuminized cloth layer may function as the lining.

(c) The alurninized cloth layer 6 may be eliminated, and in l1'euthereof, the fabric layer 4 may be provided on its lower surface With aheat reflective alurninurn coating of the character described.

(d) The layer 6 may be eliminated, and the lining 8 provided withaluminum coating.

1t is 'to be understood that the form of my invention,

heteWith shown and described, is to be taken as a. preferred exarnple ofthe same, and -that various other changes in the shape, size andarrangement of artsv may be. resorted to, without departing from the spirit of my invention, er the s'eope cf the subjoined claims.

Having thus deseribed my invention, I clai'rn:

1. In a eap of the character described, a body comjprising an upper andlower portion, said upper portion Comprising a substantially circu1arla'yer of fabric having a hem at its peripheral edge, said 1ower portionhaving a hemmed edge, and a substantially circular layer of a eloselywoverx thin flexible fabric underlying said fabric 1ayer andhaving a hemat its peripheral edge, said 'thin flexible 1ayer having an extremelythin deposit or plating pf aluminurn on its upper surface, said h'emrnededges of the fabric layer and aluminum-coated fabric being sewn to thehemmed edge cf the 1ower portion.

2. In a cap cf the eharacter described, a body compr.ising an upper andlower portion, said upper portion .cornprising a 1ayer of fabrie havinga hem at its peripheral edge, said 1ower portion having a hemmed edge, a1ayer of closely woven (hin flexible cloth underlying said first layerand having a thin coting of aluminum 4 thereon, said second layer havinga hem at its peripheral edge, said hemmed edges of the fabric layer andaluminum coated cloth being sewn to the hemmed edge of the lowerportion, and a protective strip underlying said hems and sewn thereto.
